WALLPAPER CLEANER Filed Feb. 13, 1939 g] wu c wtom Patented Dec. 17, 1940 UNITED STATES PATENT. OFFICE.

3 Claims.

My invention relates to wall cleaners and more particularly to wallpaper cleaners using the usual dough or paste cleaner as the cleansing medium and utilizing my invention to knead and mold the dough or paste into a proper form for use continually mixing and molding the paste for each successive stroke.

A further object of my invention is to provide a. hand operated device for cleansing walls and ceilings with paste cleaners without the necessity of the use of ladders etc. and which device will be easily used and operated.

A still further object is to provide a wallpaper cleaning device using paste cleaner and which device catches all droppings from the cleaner after each successive stroke of the cleaner over the surface being cleaned.

These and other objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawing,

Figure 1 is a side elevation of the device ready for loading the paste thereinto.

Figure 2 is a vertical transverse section through the device showing the use of the paste cleaner therein and the form it takes when being used.

Figure 3 is a face view of the device reduced in size.

Figure 4 is a back view of Figure 3.

Figure 5 is a view of the back removed from the device.

In the drawing I have shown my device as made with a rectangular case A having the bottom 5 closed and with the front side 6 extended up about half way and then curved inwardly at l to form a parting edge la, for cleaning all paste from the lower of my two rolls. The ends 8 and 9 of the-device extend upwardly to make ends for the case and to act as supports for the rolls. The back of the case is left open and is closed by a removable back l0, said back having the top portion sloping backwardly at I l away from the vertical alignment of the case and the extreme top of this sloping portion carries a longitudinal dove tail channel l2 in which a removable brush I3 is inserted, said brush having it back formed to fit the channel [2 and with the bristles I4 of the brush extending upwardly to act as a brush for removing small particles of the paste cleaner from the walls.

Longitudinally of the case A and extending from end to end I provide two spaced apart rolls B and C. The upper roll B is set forward in the case over the front wall of the case A, and the roll is longitudinally grooved with spaced apart 5 clove tail grooves l1, said grooves to hold the paste firmly in place on the roll. The bottom roll C is made with a smooth surface and acts only as a complementary roll forming the paste into an even thickness as it is passed between the two 10 rolls.

This action both regulates the thickness of the paste and also kneads the paste thoroughly, mixing it each time it passes between the rolls and as the paste is placed on the rolls in suflicient quan- 1'5 tity to completely surround the roll B it is constantly being mixed and kneaded. These rolls are mounted on stub shafts which extend through the ends of the case and one end of these shafts is provided with operating pinions shown as BI and 2 CI in Figure l of the drawing. These pinions are controlled and rotated by toothed pawls I8 and 23. The pawl I8 for driving the pinion BI is mounted to a lever plate 20 which plate is pivoted on the stub' shaft of the roll B and adapted to rotate freely thereon inside the pinion BI so that every movement of the plate is transmitted to the pawl.

'A like lever plate 22 is mounted on the shaft of the roll 0 to which the pawl 23 is pivotally mounted, said pawl having the teeth thereof to mesh with the teeth of the pinion gear CI.

The two plates 20 and 22 are connected by a cross link 24 for simultaneous action and a spring 25 is connected to alink 26 which link is attached to the opposite side of the lever 22, the spring being to return the levers to their initial position after each operation of the lever for actuating the device which will be described hereafter.

Actuating wires or cables 28 and 29 are connected to a whiifletree 30 at one end and to the free ends of the two pawls I8 and 23 at their other ends, thus with each movement of the Whiflletree the cables are drawn down and the pawls actuated simultaneously, actuating the two lever plates 20 and 22 and thereby the pinion gears, causing both of the rolls to rotate at the same time.

A main control wire or cable 3| is attached to the center of the whifiletree and is attached to a handle'lever 32 which lever is pivotally attached to the lower or hand control end of a handle D for the entire device. The top end of the handle is attached in a U-shaped socket 36 formed on rotation of the rolls.

the bottom side of the case A, thus providing a handle for the entire device. This socket 36 is provided with extended legs on each side of the handle and is perforated by several holes 31 through which the securing bolt 38 may be passed which permits changing the angle relation of the entire case to the handle to enable the user to use the device where and how he desires. A top bolt 39 holds the end of the handle in the socket.

The operation of the device is a follows:

Paste cleaner is pressed into and around the top roll B and into the longitudinal slots or grooves I! while the hand lever is actuated to cause the roll to turn until the paste cleaner is entirely surrounding the roll B.

The device is then ready for use and may be used in the following manner:

The person using the device grasps the handle in one hand then using the other hand on the base or end of the handle D and the lever 32 he draws the paste cleaner across or down the wall to be cleaned and after each stroke of the cleaner he actuates the hand lever 32. This pulls down on the cable 3| drawing the whifiletree down and actuating the two lever plates and the two pawls thereby, causing the turning of the two rolls and presenting a new surface for each successive stroke of the cleaner and at the same time all of the material will be kneaded with each successive Should any of the paste be drawn off from the surface of the roll of paste cleaner it will fall into the case through the space between the back and case so that no muss will be made when the device is used.

As shown in Figure 2 each successive rotation causes sluffiing off of some of the paste and drawing back of other parts thereof so that when the two rolls are turned this accumulated material at the back of the top roll will be thoroughly mixed and properly conditioned for each successive stroke of the device.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. In a paste cleaner handling device, of the class described, the combination of a case having the ends raised above the sides and with the front curved inwardly to form a parting edge; spaced apart parallel rolls carried between said ends with the upper roll extended forward from the case and in that space above the curved in portion of the front; spaced apart parallel dove tail grooves extending longitudinally in said upper roll to retain the paste cleaner; a removable back for said case; means to rotate each roll simultaneously after each successive stroke of the cleaner over the surface to be cleaned.

2. A wall paper cleaner comprising spaced apart parallel rolls one of which is provided with longitudinally disposed spaced apart parallel dove tail grooves adapted to receive and hold paste cleaner onto the surface thereof; means to support said rolls in a case; means to catch droppings from said paste into said case; and ratchet means to rotate the rolls simultaneously to reshape the cleaner betwen the rolls, and present a fresh surface for each successive stroke thereof.

3. A wall paper paste cleaner of the class described comprising, a rectangular casing having a removable back with the back extending longer than the ends and front and with the front bent back in a curved parting edge; spaced apart parallel rolls mounted longitudinally in said casing with shafts extending into the ends of the casing as bearing supports for the rolls; longitudinally disposed dove tail grooves formed in the upper roll, said roll to receive the cleaner paste and form it between the two rolls with each successive stroke, the parting strip on the front to insure a uniform thickness to the paste; ratchets on one end of each roll support shaft; coacting dogs engaging each ratchet; compound levers to operate said do s and thereby said ratchets simultaneously; a handle for operating said cleaner mounted in the bottom of said case; a hand grip lever mounted on the end of said handle; and means to connect the grip lever with the coacting levers to cause the rolls to rotate with each actuation of the hand grip lever.
